POLE FOR ELECTRIC WIRES.

SPECIFICATION forming part of Letters Patent No. 415,325, dated November 19, 1889.

Application filed September 19, 1889- Serial No. 3 ,410. (No model.)

To all whom it may concern:

Be it known that I, LEVI RAVVSON GREENE, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Pole for Electric \Vires and other Pu rposes, of which the following is a specification, reference being had to the accompanying drawing, in which a sectional elevation of a pole embodying my invention is shown.

My present invention is an improvement upon that described in my pending application, Serial No. 315,899, filed June 28, 1880; and it consists of two or more lengths of pipe of different diameters, the external diameter of the smaller pipe being enlarged at one end to equal that of the larger pipe and the enlarged end being welded to the end of the next section.

In the drawing I have shown a pole made of three sections A A A one end of section A being enlarged so that its diameter equals that of A, and the two being then welded together in a manner now too well understood to require description. One end of section A is also enlarged to fit the end of section A, and they are also Welded together. The three sections thus united form a pole which is very durable, not too heavy, is readily made, and can be given the taper desired by simple processes well known to those skilled in metal working.

Vhat I claim as my invention is The pole above described, made up of a pinrality of pipes of different diameters, the smaller being enlarged at one end to the diameter of the larger and the enlarged end of one pipe being welded to the end of the next pipe, all substantially as described.
